Chikungunya in the Americas
Updates of chikungunya case counts are publically released every Tuesday evening (MT).

As of July 18, 2014, local transmission had been identified in 24 countries or territories in the Caribbean, Central America, South America, or North America. A total of 436,586 suspected and 5,724 laboratory-confirmed chikungunya cases had been reported from these areas (Updated data from the Pan American Health Organization ).
Chikungunya virus likely will continue to spread to new areas in the Americas (North America, Central America, and South America) through infected people and mosquitoes.
The mosquitoes that transmit the virus are found throughout much of the Americas, including parts of the United States.
Since chikungunya virus is new to the Americas, most people in the region are not immune. This means they can be infected and spread the virus to other mosquitoes.
